So, I just bought a 1977 Champagne? convertible Triple White

[chrisarnt]

Can anyone decode this vin for me?
I did try and figure it out, but could not.

Stop solid with a clunk?, or growing resistance like a spring?

There's not much to decode from a VIN, it's for a 77 convertible if that's what you are concerned about.

Don'r force anything past a clunk, I assume the spark plugs are out when you are doing this?

Next step is remove the rocker covers and see if any of the lifters get really loose at various segments of your turning, could be a valve stuck open.

Maybe, combined with some lube through the injector mounting hole tapping on the valve with a soft hamer may get it moving again make sure that piston is near the bottom of it's stroke though.[/quote]

Duh... I will pull the covers and tell you what happens.

Am I correct in thinking that the suspect side is the one that had the rusty plug?

As far as getting some lube on that valve What about just flooding the crap out of the cylinder with mystery oil with tube the size of the plug hole taped tight onto the bottle. Then when the cylinder is full give the bottle a good long squeeze to flood the valves?
Does that make sense?

Then give it a little tappy tap.

Then take the next step.

Worth a try, but remember you have to get whatever you put in there out after as well. I was thinking a penetrant that fizzes or foams up, putting it down the intake (if that's the valve that's siezed) gets it on the guide where all the bad action likely is. If it's the exhaust then some sort of foaming lube in the cylinder would be the better way to get at that.

But in the end if it's stuck odds are other things didn't do too well when the moisture got in that cylinder either, it may be telling you it's time to pull the heads for a look. A golden opportunity to replace the pushrod seals if nothing else since there's a great chance they'll leak.

I hear what you are saying.

Pulling the head is a winter project.

At the moment I just want to get it on the road, even if just a few spins around the block to see whats what...
I think I need to get my vw buddy over for a look see.


As far as "the pushrod seals if nothing else since there's a great chance they'll leak." Forgive my ignorance.. is that a seized motor problem or a smoke like hell problem?

Also, what kind of foaming lube would you recommend?

I'm kind of assuming that any extra lube will just work it's way out and smoke like hell..

I have to admit I will be disappointed if there isnt some major smoking (at least initially ) when I fire this think up.

Leaky pushrod tubes are messy but not terminal, lost of drips where you park and stinky heater, often hardened up on engines that have been sitting and they start piddling shortly after reanimation.
As Randy mentioned earlier also consider blocked cooling fins from assorted nests and debris.

As for foaming lube I'm not sure, I had some stuff years ago called engine storage spray that fizzed up and filled the cylinder when you sprayed it into a plug hole. There's also some penetrating oils that also fizz up but I can't recall the exact brand at the moment.

Myself if it puts up any kind of fight I'd give up on the drive around the block and pull it for a deeper peek. Between the chance of blocked fins and possible risk of stuck parts breaking off and damaging more parts sometimes it's just not worth the potential extra expense for a few minutes of running that only confirms it needed to come apart anyways.

Wise words.

The heater ducts have been taped off on the engine.
I will take a look and run the blower through to see if it's restricted.


It's too late to think about the valve right now.

I got some Seafoam penetrating lube that sounds like it foams from the label.
I didn't try it last night because I ended up stopping at a strip club on the way home... And on the way home from that I stopped at the supermarket and bought a strip steak...
IT was a good night.

[busdaddy]

I completely understand, there's always time for the tittybar

It's not just the heater ducts, the fan inlet as well as a few other places you'd never imagine are access points, those little buggers will deconstruct the seats or something nearby and pile it all into some deep recess in there, likely stash some nuts or seeds for snacks as well. Have a fire extinguisher handy incase that pile catches fire.

OK. There is tape over these two vents... The air filter box was open, so that's not good.
The tape looks like it's been there for years..

Are these the vents/ducts you are all concerned about?
